The motherboard receives the sigma-delta
streams from the daughterboards which are
further elaborated by the STPMC1. This device,
from a 4.194 MHz crystal oscillator, provides a
common clock with programmable frequency to
all the daughterboards.
The motherboard, through a 10-pin flat cable
connector, can be interfaced to a microprocessor
board to implement advanced metering features
(multi-tariff, data management and storage,
communication, etc). It also has stepper motor
connectors for simple energy meter
implementation.
is connected, also to the motherboard.
On this board, the STPMS1 device senses the
phase current through a CT or a shunt sensor,
and the phase voltage through a voltage divider.
The presence of dedicated networks greatly
reduces the sampling (aliasing) noise and the
crosstalk noise between voltage and current
channels, increasing meter precision. The
STPMS1 produces a sigma-delta stream, sent
together with the supply voltage, to the STPMC1
through a card edge connector.
